What is the name of the taco filled with minced meat and potato in a tomato-based sauce?

The taco filled with minced meat and potato in a tomato-based sauce is called tacos de picadillo.

Picadillo is a minced-meat dish found across Latin America and the Philippines. Mexican picadillo commonly combines ground beef—sometimes pork or a beef-and-pork mixture—with potatoes and carrots in a sauce made from blended tomatoes, garlic, and onion. The mixture is cooked until the vegetables are tender and the sauce coats the meat, then used as a taco filling.

The name comes from the Spanish verb picar, meaning “to mince” or “chop.” Picadillo is not limited to tacos: it can fill tostadas, gorditas, chiles rellenos, tamales, empanadas, and other dishes. Regional recipes may add peas, squash, raisins, olives, or different spices.

A common mistake is confusing picadillo with tinga. Tinga usually features shredded meat cooked with tomato, onion, and smoky chipotle, whereas picadillo is defined by minced meat and often diced vegetables such as potato. The exact seasoning varies, but the minced texture is central.
